Contamination The presence in, on or under land, air or water of a substance (whether a solid, liquid, gas, odour, heat, sound, vibration or radiation) at a concentration above the concentration at which the substance is normally present in, on or under land, air or water in the same locality, that presents a risk of Environmental Harm, including harm to human health or any other aspect of the Environment, or could otherwise give rise to a risk of non-compliance with any Statutory Requirement for the protection of the Environment.
Environmental Contamination Neither Party shall in any event be liable to the other Party for any costs whatsoever resulting from the presence or release of any environmental hazard such Party did not cause or contribute to causing. Each Party shall, at the other Party's request, indemnify, defend, and hold harmless the other Party, each of its officers, directors and employees from and against any losses, damages, claims, demands, suits, liabilities, fines, penalties and expenses (including reasonable attorneys fees) that arise out of or from (i) any environmental hazard that such Party, its contractors or agents caused in the work locations or (ii) the presence or release of any environmental hazard for which such Party is responsible under Applicable Law. In the event both Parties contribute to such environmental hazard, they shall each proportionately bear such liability.
